So there are now officially two cool things about the Opel Flextreme concept car revealed here at the Frankfurt Auto Show last night. The first would have to be the fact that the concept's a diesel-electric hybrid — and we heart the idea of mating the two fuel efficiencies together. The second is that the Flextreme has two little Segways that it stores in its rear end. It's adorable. Oh, you want to know more? Check after the jump.

"The Flextreme takes the new design language debuted in the GTC Coupé at the Geneva Motor Show several steps further. With the forward-opening rear doors (FlexDoor®), a large transparent roof and two tailgate doors that open from the side and swing upwards, the concept car continues Opel's tradition of particularly flexible and practical body concepts with attractive designs. This also includes the innovative FlexLoad® additional underfloor luggage compartment.

The big surprise for the IAA are two high-tech electric personal transporters, ingeniously packaged below the cargo floor. They can be used in areas that cars cannot enter, thereby adding an extra mobility option. The electric scooters provide up to 38 km (23 miles) of clean mobility."
